WebAverage speed, however, is very different from average velocity. Average speed is the distance traveled divided by elapsed time. So, while the magnitudes of the instantaneous speed and velocity are always identical, the magnitudes of average speed and velocity … WebJan 26, 2012 · specific discharge. In surface water hydrology, discharge per unit area of an upstream watershed. In open channel flow, discharge per unit width of channel. In groundwater, the volumetric flow rate per unit area of a porous media, also known as flow velocity or specific flux; if computed using Darcy's law, known as Darcy's flux.

WebThe discharge at any given point in a river can be calculated as the product of the width (in ft or m) times the average depth (in ft or m) times average velocity (in ft/s or m/s). The vast majority of rivers are known to exhibit considerable variability in flow over time because inputs from the watershed, in the form of rain events, snowmelt ... WebThe discharge formula, Q = A V, can be used to rewrite Gauckler–Manning's equation by substitution for V. Solving for Q then allows an estimate of the volumetric flow rate (discharge) without knowing the limiting or actual flow velocity. The formula can be obtained by use of dimensional analysis. WebSep 25, 2024 · To compute for discharge velocity, two essential parameters are needed and these parameters are Rate of Flow (Q) and Cross-Sectional Area of Soil Mass perpendicular to Direction of Flow (A).

"WebNov 5, 2024 · Average velocity is defined as the change in position (or displacement) over the time of travel. In everyday usage, the terms “speed” and “velocity” are used interchangeably. In physics, however, they are distinct quantities. Speed is a scalar quantity and has only magnitude. Velocity, on the other hand, is a vector quantity and so has ...

Specific discharge vs average velocity

WebA discharge is a measure of the quantity of any fluid flow over unit time. The quantity may be either volume or mass. Thus the water discharge of a tap (faucet) can be measured with a measuring jug and a stopwatch. Here the discharge might be 1 litre per 15 seconds, … WebWater is flowing through the channel at an average velocity of 16 feet per second. We can determine the volumetric flow rate as follows: The flow rate will vary according to the cross-sectional area of the channel: Area = π * (Diameter) 2 / 4 Area = 3.1415926 * (8/12 ft) 2 / 4 Area = 0.349 ft 2 The area of the pipe is 0.349 ft 2.
